Letter; Patent No. 61,044, dated April 1867.

IMPROVED SEAT AND BACK.

TO ALL WHOM ITMAY OONCERN:

Be it known that I, MORTIMER L. SMITH, ofDetroit, in the county of Wayne, and of they State of Michigan, have invented a VPortable Seat and Back, to' be applied to any board seat; andI` do hereby declare that the following is a full and exact description thereof, reference being had to the annexed drawings, and the letters of reference marked thereon, in which* Figure lis a perspective view.

Figure 2, a side view.

Figure 3, a side viewrot` the chair when folded together for transportation; and

Figure 4, a front view.

To enable others skilled in the art to make and use this, my invention, I will proceed to describe its construction and operation. i

i I construct the seat and back of an ordinary chair. The upright pieces (marked E E in the drawings) which form the side of the hack, (marked BQ extend about four inches below the seat A, and are attached to it by a pivot or movable screw, F, so placed that the back of the seat may be moved forward until it is parallel with the seat, as shown in fig," in which position the whole seat will occupy the small space of about three inches in thickness of depth and sixteen by nineteen inches square, according to the'size ofthe seat and back. This back can also be thrown backward for the purpose hereinafter described, connectingthe lower ends of the pieces E E. We construct the strip D, which serves thcdouble purpose of strengthening the pieces E E,Vand

aifcrding a foot-rest for the person sitting` on-the seat in the rear. The front piece H, in the frame of 'seat A, will extend below the other pieces of frame one and one-fourth inch, or thercabonts. To each end ot' this piece we join firmly the strip C, so as to leave an open space between it (the piece C) and the side pieces G in the frame of scat.. This strip O `is nearly parallel Vwith the seat A, and runs to within a'few inches of the back thereof, so as to give the back'B the proper angle. By pushing the back -B to the rear, the space between the piece G and the strip O isclosed at the end by the lower end of the b'ack pieces E E, and the seat is securely fastened to the board on which it is intended te be placed. n

This invention iss-intended or designed to be used upon seats made of boards, similar to those used in sircuscs, fairs, &c. To place it in position push forward the back of the seat until it rests upon the seat, as shown in iig. 3; slip the seat over the board, allowing the latter to slide into the space between the piece Grand the strip C, then lift the backand carry it to the rear until the lower ends of the pieces E E press against the ends of strips C, and th scat is secured. The back B not only serves the usual purpose of the back of a' chair, but also holds the seat rmlyupon the board and prevents its disarrangement or unstcadinessY This seat is adapted for usc at fairs, menagerics, races, circuses, die., or wherever the ordinary board seats are used. Byit the narrow board is transformed in an instant into a broad, cushioned, and comfortable seat, with an easy and luxurious back; in short, the hard, rough board of the circus is made a soft and easy chair. By placing these seats in the position shown in iig. 3, they occupy very little room, and may be carried in large numbers in a single wagon.` They can be attached to ,the board in a moment, and being all in one piece, are not liable to get out of order or unfit for use. l

What Iclaim as my invention, and desire to secure by Letters Patent, is-

The combination of the strips C C, back E E B, seat A G G, and frame H D, all arranged as and for the purpose described.
